Embodiment Construction

[0021] In order to explain the overall concept of the present application more clearly, the following detailed description will be given by way of examples in combination with the accompanying drawings.

[0022] figure 1 An application scene diagram of a product surface defect detection method provided in the embodiment of this application. Such as figure 1 As shown, the production process line includes many processes, such as the surface defect detection process. In the surface defect detection area of ​​the process line, a robot arm 130 and an image acquisition device 140 fixedly connected to the robot arm 130 are provided.

[0023] On the process line, the terminal 110 sends a product surface defect detection request to the server 120, and when the product to be inspected for surface defect detection arrives at the surface defect detection area from the previous process, the server 120 sends a corresponding response to the mechanical arm 130 and the image acquisition devic...

Abstract

An embodiment of the invention provides a method and a device for detecting product surface defects. The method comprises the following steps: a server receives a request for acquiring surface information of products on a process line from a terminal; a plurality of first images containing first product surface and label data of each first image are acquired; a preset product surface defect detection model is updated according to the plurality of first images and the label data of each first image; second images, containing second product surface, from an image acquisition device are received,wherein the type of the second product corresponds to the type of the first product; the second images are identified according to the updated product surface defect detection model to determine whether the product surface in the second image has defects. By means of the technical scheme, defects of the product surface can be detected in real time in the production process of the product, the labor cost is reduced, and the flexibility degree of the whole production process is increased.

Description

technical field [0001] The present application relates to the technical field of detection, in particular to a method and device for detecting product surface defects. Background technique [0002] In the process of product production, the surface of the product and its parts will inevitably produce various types of defects, such as misalignment, scratches, pollution, etc. Therefore, product surface defect detection has become an indispensable part of the quality inspection link in the product production process. [0003] At present, the detection methods of product surface defects mainly include manual detection and machine vision detection. The manual detection method has problems such as low detection efficiency and high production cost. The way of machine vision inspection can realize the automation of surface defect detection, but the surface defect detection models in the existing machine vision inspection are only for the detection of a specific product surface or a...
